Description

Description Description
Titre de l'invention : Dispositif de distribution de liquide caloporteur Title of the invention: Heat transfer liquid dispensing device
[0001] La présente invention se rapporte au domaine des dispositifs de régulation thermique de batterie et plus particulièrement au domaine des dispositifs de distribution de liquide caloporteur pour la régulation thermique de cellules de batterie. The present invention relates to the field of battery thermal regulation devices and more particularly to the field of coolant liquid distribution devices for the thermal regulation of battery cells.
[0002] Le refroidissement de batteries fait classiquement intervenir des plaques de refroidissement positionnées en contact contre la surface des batteries destinées à être refroidies. Chacune de ces plaques de refroidissement présente une structure creuse à l’intérieur de laquelle un fluide caloporteur est mis en circulation. Le contact d’une plaque de refroidissement contre la surface d’une batterie permet d’optimiser les échanges thermiques entre les deux surfaces. Le fluide caloporteur en déplacement à l’intérieur d’une plaque de refroidissement permet alors une extraction de la chaleur transférée depuis une batterie vers la plaque de refroidissement. La circulation de fluide caloporteur permet ainsi d’opérer un maintien optimisé des échanges thermiques entre une batterie et la plaque de refroidissement avec une extraction continue de la chaleur. [0002] The cooling of batteries conventionally involves cooling plates positioned in contact against the surface of the batteries intended to be cooled. Each of these cooling plates has a hollow structure inside which a heat transfer fluid is circulated. The contact of a cooling plate against the surface of a battery makes it possible to optimize the heat exchanges between the two surfaces. The heat transfer fluid moving inside a cooling plate then allows an extraction of the heat transferred from a battery to the cooling plate. The circulation of heat transfer fluid thus makes it possible to operate an optimized maintenance of the thermal exchanges between a battery and the cooling plate with a continuous extraction of the heat.
[0003] A l’intérieur des plaques de refroidissement, le fluide caloporteur opère un déplacement entre deux orifices, d’entrée et de sortie, disposés au niveau d’au moins une extrémité des plaques. Le fluide caloporteur se trouve réparti entre différentes plaques de refroidissement disposées parallèlement entre elles par des conduits de distribution qui, d’une part, alimentent les orifices d’entrée de chacune des plaques de refroidissement et, d’autre part, récupèrent le fluide caloporteur au niveau des orifices de sortie de ces plaques. Ces conduits de distribution, d’alimentation et d’extraction, présentent classiquement une structure rectiligne de section sensiblement circulaire, qui comprend une pluralité d’orifices dont les formes respectives sont complémentaires de celle des orifices, d’entrée et de sortie, portés par chacune des plaques à au moins une de ses extrémités. Les conduits de distribution sont ainsi soudés à chacune des plaques au niveau de la périphérie de chacun des orifices, d’entrée et de sortie. Toutefois, une telle méthode d’assemblage du conduit de distribution avec les plaques de refroidissement, si elle présente une efficacité notoire en matière d’étanchéité, fait également rencontrer des difficultés à un utilisateur qui souhaite intervenir au niveau de cette jonction, notamment dans le cadre d’une opération de maintenance. En effet, de par sa position spécifique entre les deux éléments réunis que sont un orifice du conduit de distribution et un orifice de la plaque de refroidissement, la soudure présente un défaut d’accessibilité qui complique la séparation de ces deux éléments. Par ailleurs, une soudure impose un détachement de ces éléments avec une rupture de la jonction et/ou avec une cassure du conduit de distribution. Aussi, lorsqu’un utilisateur se doit d’effectuer le remplacement d’un conduit rompu en raison d’une soudure, un tel assemblage par soudure n’autorise pas une séparation rapide et facilitée. En conséquence, l’utilisateur est contraint à retirer l’intégralité de l’élément rompu pour le substituer par un nouvel élément, quand bien même cette rupture du conduit serait ponctuelle et très localisée. [0003] Inside the cooling plates, the heat transfer fluid moves between two orifices, inlet and outlet, arranged at at least one end of the plates. The heat transfer fluid is distributed between various cooling plates arranged parallel to each other by distribution ducts which, on the one hand, supply the inlet orifices of each of the cooling plates and, on the other hand, recover the heat transfer fluid at the exit orifices of these plates. These distribution, supply and extraction conduits conventionally have a rectilinear structure of substantially circular section, which comprises a plurality of orifices whose respective shapes are complementary to that of the inlet and outlet orifices carried by each of the plates at at least one of its ends. The distribution ducts are thus welded to each of the plates at the level of the periphery of each of the inlet and outlet orifices. However, such a method of assembling the distribution duct with the plates of cooling, if it has a notorious efficiency in terms of sealing, also causes difficulties for a user who wishes to intervene at this junction, in particular in the context of a maintenance operation. Indeed, due to its specific position between the two joined elements which are an orifice of the distribution duct and an orifice of the cooling plate, the weld has an accessibility defect which complicates the separation of these two elements. Furthermore, a weld imposes a detachment of these elements with a break in the junction and/or with a break in the distribution duct. Also, when a user has to perform the replacement of a pipe broken due to a weld, such an assembly by welding does not allow quick and easy separation. Consequently, the user is forced to remove the entire broken element in order to replace it with a new element, even if this rupture of the duct is occasional and very localized.
[0004] La présente invention a pour but de pallier ces inconvénients en proposant une solution d’assemblage du conduit de distribution d’avec la plaque de refroidissement qui permette d’opérer une installation et une séparation facilitée tout en garantissant une étanchéité de la jonction entre ces deux éléments sans risque d’altération du conduit de distribution. The purpose of the present invention is to overcome these drawbacks by proposing a solution for assembling the distribution conduit with the cooling plate which makes it possible to operate an installation and a facilitated separation while guaranteeing a tightness of the junction. between these two elements without risk of altering the distribution duct.
[0005] L’invention a ainsi pour objet un dispositif de distribution de liquide caloporteur au niveau d’orifices de circulation de plaques de refroidissement, caractérisé en ce que le dispositif comprend au moins : [0005] The object of the invention is thus a device for distributing heat transfer liquid at the level of circulation orifices of cooling plates, characterized in that the device comprises at least:

- un joint positionné le long d’au moins une partie de la surface d’appui du conduit, ce joint étant configuré pour étanchéifier la jonction de l’orifice de distribution du conduit avec une plaque de refroidissement, - a gasket positioned along at least part of the support surface of the duct, this gasket being configured to seal the junction of the distribution orifice of the duct with a cooling plate,

The invention also relates to an assembly which comprises at least one dispensing device according to the invention attached to at least one cooling plate.

- un orifice de distribution 41 configuré pour être positionné en vis-à-vis d’au moins un orifice de circulation 91 d’une plaque de refroidissement 9, - a distribution orifice 41 configured to be positioned opposite at least one circulation orifice 91 of a cooling plate 9,
- une surface d’appui 42 configurée pour être de forme complémentaire à la portion de la surface 92 de la plaque de refroidissement 9 qui porte au moins un orifice de circulation 91 , cette surface d’appui 42 entourant au moins une partie de l’orifice de distribution 41 du conduit 4, - a support surface 42 configured to be of complementary shape to the portion of the surface 92 of the cooling plate 9 which carries at least one circulation orifice 91, this support surface 42 surrounding at least part of the distribution orifice 41 of conduit 4,
- un joint 2 positionné le long d’au moins une partie de la surface d’appui 42 du conduit 4, ce joint 2 étant configuré pour étanchéifier la jonction de l’orifice de distribution 41 du conduit 4 avec une plaque de refroidissement 9, un moyen de fixation 3 du conduit 4 à la surface d’une plaque de refroidissement 9. - a gasket 2 positioned along at least part of the support surface 42 of the duct 4, this gasket 2 being configured to seal the junction of the distribution orifice 41 of the duct 4 with a cooling plate 9, means 3 for fixing conduit 4 to the surface of a cooling plate 9.
[0012] Le dispositif de distribution 1 selon l’invention est ainsi réalisé par la combinaison d’un conduit 4 de distribution avec un joint 2 et un moyen de fixationThe distribution device 1 according to the invention is thus produced by the combination of a distribution conduit 4 with a joint 2 and a fixing means
3 arrangés pour coopérer avec la surface d’une plaque de refroidissement 9 au niveau d’un orifice de circulation 91. Le dispositif de distribution 1 est configuré pour opérer une jonction étanche avec la plaque de refroidissement 9 par l’intermédiaire d’un joint 2 d’étanchéité notamment positionné en compression entre le conduit 4 de distribution du liquide caloporteur et la surface de la plaque de refroidissement 9. Le joint 2 étanche est réalisé dans un matériau élastique par exemple un matériau de type silicone ou caoutchouc. Le moyen de fixation 3 est configuré pour opérer un maintien du conduit 4 assemblé à la plaque de refroidissement 9 de sorte qu’au moins une partie du bord périphérique de l’orifice de distribution 41 du conduit 4 soit appuyée contre une surface du joint 2 étanche, une surface opposée du joint 2 étanche étant en appui contre une partie du bord périphérique de l’orifice de circulation 91 d’une plaque de refroidissement 9. Cette étanchéification par compression du joint 2 entre les surfaces du conduit3 arranged to cooperate with the surface of a cooling plate 9 at the level of a circulation orifice 91. The dispensing device 1 is configured to effect a sealed junction with the cooling plate 9 by means of a joint 2 sealing in particular positioned in compression between the duct 4 for distributing the heat transfer liquid and the surface of the cooling plate 9. The sealed seal 2 is made of an elastic material, for example a material of the silicone or rubber type. The fixing means 3 is configured to maintain the pipe 4 assembled with the cooling plate 9 so that at least part of the peripheral edge of the dispensing orifice 41 of the pipe 4 is pressed against a surface of the joint 2 sealed, an opposite surface of the seal 2 being sealed against a part of the peripheral edge of the circulation orifice 91 of a cooling plate 9. This sealing by compression of the seal 2 between the surfaces of the duct
4 et de la plaque de refroidissement 9 sur la périphérie des orifices de distribution 41 et de circulation 91 autorise, grâce à l’élasticité du joint 2, une relative flexibilité du positionnement entre eux des deux éléments assemblés, en dépit du maintien assuré par le moyen de fixation 3. De plus, le joint 2 d’étanchéité est réalisé sous la forme d’une structure sensiblement circulaire, par exemple annulaire, de façon à permettre un cloisonnement périphérique de l’espace ou du volume qui sépare les deux orifices, de distribution 41 et de circulation 91 , respectivement portés par le conduit 4 de distribution et la surface de la plaque de refroidissement 9. Grâce à un tel cloisonnement de l’espace ou du volume entre le conduit 4 de distribution et la surface de la plaque de refroidissement 9 au niveau de leurs orifices 41 , 91 respectifs, il n’est pas nécessaire que ces orifices 41 , 91 présentent des contours et formes qui soient strictement identiques. En effet, les contours et formes des orifices de distribution 41 et de circulation 91 sont susceptibles de présenter des différences dès lors que chacun de ces deux orifices 41 , 91 disposés en vis-à-vis l’un de l’autre demeure positionné à l’intérieur du bord intérieur du joint 2 étanche. [0013] Le moyen de fixation 3 est préférentiellement configuré pour opérer un assemblage réversible du conduit 4 à la surface d’une plaque de refroidissement 9. Cette réversibilité du moyen de fixation 3 autorise ainsi une séparation facilitée des éléments réunis, notamment lorsque l’un des deux éléments doit être remplacé. Selon différentes alternatives, le moyen de fixation 3 est susceptible d’être indépendant du conduit 4 et de la plaque de refroidissement 9 ou, au contraire, d’être fixe avec l’un ou l’autre de ces deux éléments. 4 and the cooling plate 9 on the periphery of the distribution orifices 41 and circulation 91 allows, thanks to the elasticity of the joint 2, a relative flexibility of the positioning between them of the two assembled elements, in spite of the maintenance provided by the fixing means 3. In addition, the seal 2 is made in the form of a substantially circular structure, for example annular, so as to allow peripheral partitioning of the space or volume which separates the two orifices, distribution 41 and circulation 91, respectively carried by the distribution conduit 4 and the surface of the cooling plate 9. Thanks to such partitioning of the space or volume between the distribution conduit 4 and the surface of the cooling plate cooling 9 at their respective orifices 41, 91, it is not necessary that these orifices 41, 91 have contours and shapes that are strictly identical. Indeed, the contours and shapes of the distribution orifices 41 and circulation 91 are likely to present differences since each of these two orifices 41, 91 arranged opposite one another remains positioned at inside the inner edge of the seal 2 tight. [0013] The fixing means 3 is preferably configured to operate a reversible assembly of the conduit 4 to the surface of a cooling plate 9. This reversibility of the fixing means 3 thus allows easier separation of the joined elements, in particular when the one of the two elements must be replaced. According to different alternatives, the fixing means 3 is capable of being independent of the duct 4 and of the cooling plate 9 or, on the contrary, of being fixed with one or the other of these two elements.
[0014] Selon un exemple de construction se rapportant à une variante particulière du dispositif de distribution 1 selon l’invention, la surface d’appui 42 du conduit 4 au niveau de laquelle le joint 2 est positionné, comprend un logement 43 apte à recevoir au moins une partie du joint 2. Selon cette variante, la surface d’appui 42 du conduit 4 qui exerce une compression du joint 2 présente une cavité réalisant un logement 43 de forme et contour sensiblement complémentaire à la forme et au contour du joint 2. Selon une spécificité de construction, au moins une partie des dimensions de ce logement 43 est sélectionnée pour autoriser une déformation du joint 2 en compression à l’intérieur du logement 43. Selon une spécificité de construction alternative, voire éventuellement complémentaire, au moins une partie des dimensions de ce logement 43 est sélectionnée pour maintenir une partie du joint 2 en compression lorsque le joint 2 se trouve positionné dans celle-ci. Selon cette spécificité de construction, la partie du joint 2 en compression correspond sensiblement à la partie du joint 2 insérée dans le logement 3. Cette compression de la partie du joint 2 insérée permet d’opérer un pincement du joint 2 par une partie du logement 43, de sorte que le joint 2 est en mesure d’être maintenu en position à l’intérieur du logement 43. Le pincement et/ou la compression du joint 2 inséré par des bords opposés du logement 43, est effectué dans un plan sensiblement perpendiculaire à l’axe de compression du joint 2 entre le conduit 4 de distribution et la plaque de refroidissement 9. Il convient de relever que la profondeur de cette cavité réalisant un logement 43 est définie de sorte que, lorsque le joint 2 est comprimé, l’épaisseur du joint 2 demeure suffisante pour que le joint 2 dépasse le niveau formé par la surface d’appui 42. According to an example of construction relating to a particular variant of the dispensing device 1 according to the invention, the support surface 42 of the conduit 4 at which the seal 2 is positioned, comprises a housing 43 capable of receiving at least a part of the seal 2. According to this variant, the support surface 42 of the conduit 4 which exerts a compression of the seal 2 has a cavity forming a housing 43 of shape and outline substantially complementary to the shape and the outline of the seal 2 According to a construction specificity, at least a part of the dimensions of this housing 43 is selected to allow a deformation of the seal 2 in compression inside the housing 43. According to an alternative construction specificity, even possibly complementary, at least one part of the dimensions of this housing 43 is selected to maintain part of the seal 2 in compression when the seal 2 is positioned therein. According to this construction specificity, the part of the seal 2 in compression corresponds substantially to the part of the seal 2 inserted into the housing 3. This compression of the inserted part of the seal 2 makes it possible to operate a pinching of the seal 2 by a part of the housing 43, so that the joint 2 is able to be held in position inside the housing 43. The pinching and/or the compression of the joint 2 inserted by opposite edges of the housing 43, is carried out in a plane substantially perpendicular to the axis of compression of the seal 2 between the distribution duct 4 and the cooling plate 9. It should be noted that the depth of this cavity forming a housing 43 is defined so that, when the seal 2 is compressed, the thickness of seal 2 remains sufficient for seal 2 to exceed the level formed by bearing surface 42.
[0015] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques de la variante précédemment énoncée, la surface d’appui 92 de la plaque de refroidissement 9 au niveau de laquelle le joint 2 se trouve positionné, comprend un logement 93 apte à recevoir au moins une partie du joint 2. Il convient de relever que, dans le cadre de cette variante particulière de construction, le logement 93 est réalisé par une cavité de forme et contour sensiblement complémentaire à la forme et au contour du joint 2. Cette cavité formant logement 93 est alors susceptible d’adopter des caractéristiques dans sa construction et ses interactions avec le joint 2 qui reproduisent de façon sensiblement similaire, sinon identique, les caractéristiques de la cavité précédemment détaillée et se rapportent à la surface d’appui 42 du conduit 4. Il convient de relever que la profondeur de cette cavité réalisant un logement 93 est définie de sorte que, lorsque le joint 2 est comprimé, l’épaisseur du joint 2 demeure suffisante pour que le joint 2 dépasse le niveau formé par la surface d’appui 92 de la plaque de refroidissement 9. According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variant, the support surface 92 of the cooling plate 9 at which the seal 2 is positioned, comprises a housing 93 capable of receiving at least a part of the seal 2. It should be note that, in the context of this particular variant of construction, the housing 93 is produced by a cavity of shape and contour substantially complementary to the shape and contour of the seal 2. This cavity forming a housing 93 is then likely to adopt characteristics in its construction and its interactions with the seal 2 which reproduce in a substantially similar, if not identical, manner the characteristics of the previously detailed cavity and relate to the support surface 42 of the duct 4. It should be noted that the depth of this cavity forming a housing 93 is defined so that, when the gasket 2 is compressed, the thickness of the gasket 2 remains sufficient for the gasket 2 to protrude the level formed by the bearing surface 92 of the cooling plate 9.
[0016] De même selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention, le joint 2 coopère avec le conduit 4 de distribution et la plaque de refroidissement 9, de sorte que chacun de ces deux éléments comprennent une cavité respective qui, positionnées en vis-à-vis, réalisent deux parties d’un logement à l’intérieur desquelles deux parties du joint 2 se trouvent positionnées. Le cumul des profondeurs de chacune de ces deux cavités positionnées en vis-à-vis est défini de telle sorte que, lorsque le joint 2 est comprimé, l’épaisseur du joint 2 demeure suffisante pour empêcher que les surfaces d’appui 42, 92 respectives du conduit 4 de distribution et de la plaque de refroidissement 9 ne réalisent pas un contact direct mais demeurent espacées l’une de l’autre par le joint 2 d’étanchéité. Similarly, according to an example of construction relating to another particular variant of the dispensing device 1 according to the invention, the seal 2 cooperates with the conduit 4 of distribution and the cooling plate 9, so that each of these two elements comprise a respective cavity which, positioned facing each other, form two parts of a housing inside which two parts of the joint 2 are positioned. The accumulation of the depths of each of these two cavities positioned opposite each other is defined such that, when the gasket 2 is compressed, the thickness of the gasket 2 remains sufficient to prevent the bearing surfaces 42, 92 respective distribution conduit 4 and the cooling plate 9 do not make direct contact but remain spaced from each other by the gasket 2 sealing.
[0017] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques des variantes précédemment énoncées, au moins une portion du joint 2 est réalisée en éthylène-propylène-diène monomère également appelé EPDM, en butadiène-acrylonitrile hydrogéné également appelé HNBR et/ou en silicone. L’éthylène-propylène-diène monomère ou EPDM, comme les matériaux préférentiellement sélectionnés pour participer à la réalisation du joint 2 d’étanchéité présente comme propriété d’avoir une bonne résistance chimique à un composé tel que le glycol, un fluide présentant des propriétés caloporteur particulièrement intéressante. Par ailleurs, ces matériaux présentent également des propriétés élastiques qui assurent au joint 2 une tenue dans le temps notamment face aux efforts en compression exercés entre le conduit 4 et la plaque de refroidissement 9. According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variants, at least a portion of the seal 2 is made of ethylene-propylene -diene monomer also called EPDM, hydrogenated butadiene-acrylonitrile also called HNBR and/or silicone. Ethylene-propylene-diene monomer or EPDM, as the materials preferentially selected to participate in the production of the seal 2 has the property of having a good chemical resistance to a compound such as glycol, a fluid with particularly interesting heat transfer properties. Furthermore, these materials also have elastic properties which ensure that the seal 2 holds up over time, in particular against the compressive forces exerted between the conduit 4 and the cooling plate 9.
[0018] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques des variantes précédemment énoncées, en section au niveau d’un orifice de distribution 41 destiné à être positionné en vis-à- vis d’une plaque de refroidissement 9, le conduit 4 présente une forme en « U » comprenant une portion avec un arrangement sensiblement semi-circulaire ouvert vers l’orifice de distribution 41 destiné à être cloisonné par la surface de la plaque de refroidissement 9. Selon cette variante de construction, l’ouverture qui forme un orifice de distribution 41 est positionnée sur la surface périphérique du conduit 4 selon un arrangement particulier pour permettre une construction facilitée et une coopération optimisée avec une plaque de refroidissement 9. Ce conduit 4 présente ainsi, au niveau de portions de sa longueur destinées à être en contact avec une plaque de refroidissement 9, c’est-à-dire notamment au niveau de portions de sa longueur positionnées sur la périphérie de l’orifice de distribution 41 , un arrangement qui, dans un plan en section sensiblement perpendiculaire à l’axe du flux dans le conduit 4, présente une forme de conception simple à produire. Cet arrangement selon une forme en « U », c’est- à-dire comprenant, d’une part, un côté cloisonné et, d’autre part, un côté ouvert qui réalise l’orifice de distribution 41 , permet d’obtenir deux portions de la surface d’appui 42 en extrémité des jambes du « U » susceptibles d’être disposées de part et d’autre de l’orifice de distribution 41 . De plus, un arrangement dans lequel les jambes du « U » présentent des hauteurs sensiblement similaires sur l’ensemble de la longueur de la portion de conduit 4 apporte comme avantage de permettre un positionnement facilité du conduit 4 contre la surface d’une plaque de refroidissement 9. Il convient de relever que, si dans chacun des exemples illustrés par les différentes figures, le côté cloisonné présente un arrangement arrondi, une construction présentant une configuration alternative, par exemple avec différents angles, est susceptible d’être envisagée sans pour autant sortir du dispositif de l’invention. According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variants, in section at the level of a dispensing orifice 41 intended to be positioned opposite a cooling plate 9, the duct 4 has a "U" shape comprising a portion with a substantially semi-circular arrangement open towards the dispensing orifice 41 intended to be partitioned by the surface of the cooling plate 9. According to this construction variant, the opening which forms a distribution orifice 41 is positioned on the peripheral surface of the duct 4 according to a particular arrangement to allow easier construction and optimized cooperation with a cooling plate. cooling 9. This conduit 4 thus has, at portions of its length intended to be in contact with a cooling plate t 9, that is to say in particular at the level of portions of its length positioned on the periphery of the dispensing orifice 41, an arrangement which, in a plane in section substantially perpendicular to the axis of the flow in the duct 4, features a design form that is simple to produce. This arrangement in a "U" shape, that is to say comprising, on the one hand, a partitioned side and, on the other hand, an open side which forms the dispensing orifice 41, makes it possible to obtain two portions of the support surface 42 at the end of the legs of the "U" capable of being arranged on either side of the dispensing orifice 41 . In addition, an arrangement in which the legs of the "U" have substantially similar heights over the entire length of the duct portion 4 has the advantage of allowing easy positioning of the duct 4 against the surface of a cooling 9. It should be noted that, if in each of the examples illustrated by the various figures, the partitioned side presents a rounded arrangement, a construction presenting an alternative configuration, for example with different angles, is likely to be considered without departing from the device of the invention.
[0019] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques des variantes précédemment énoncées, en section au niveau d’une portion du conduit 4 ne portant pas d’orifice de distribution 41 , le conduit 4 présente un arrangement totalement cloisonné, voire sensiblement circulaire. Une telle portion de conduit 4 est réalisée notamment au niveau de parties du conduit 4 destinées à être positionnées, par rapport au sens du flux prévu dans le conduit 4, en amont ou en aval des parties du conduit 4 qui interagissent avec la plaque de refroidissement 9. La forme de ces portions cloisonnées du conduit 4, dans un plan en section sensiblement perpendiculaire à l’axe du flux dans le conduit 4, est susceptible d’être de tout type. Toutefois, selon un exemple spécifique de construction, lorsque le conduit 4 de distribution présente une structure unique, la forme adoptée par les portions cloisonnées du conduit 4 est préférentiellement configurée pour opérer une continuité de surface avec les portions du conduit 4 qui portent des orifices de distribution 41 au niveau d’une partie majoritaire de la surface du conduit 4. According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variants, in section at a portion of the conduit 4 not bearing no dispensing orifice 41, conduit 4 has a completely partitioned, or even substantially circular, arrangement. Such a portion of duct 4 is produced in particular at the level of parts of duct 4 intended to be positioned, with respect to the direction of the flow provided in duct 4, upstream or downstream of the parts of duct 4 which interact with the cooling plate. 9. The shape of these partitioned portions of conduit 4, in a sectional plane substantially perpendicular to the axis of the flow in conduit 4, is likely to be of any type. However, according to a specific example of construction, when the distribution duct 4 has a single structure, the shape adopted by the partitioned portions of the duct 4 is preferably configured to operate a surface continuity with the portions of the duct 4 which carry orifices of distribution 41 at the level of a major part of the surface of the conduit 4.
[0020] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques des variantes précédemment énoncées, le moyen de fixation 3 comprend une pluralité de pièces de clipsage, d’agrafes, ou de vis réparties sur la longueur du conduit 4 de distribution de sorte que chaque pièce du moyen de fixation 3 opère un ancrage de l’orifice de distribution 41 avec la surface de la plaque de refroidissement 9. Selon la spécificité du moyen de fixation, l’ancrage du conduit 4 à la plaque de refroidissement 9 est susceptible de faire intervenir des arrangements ou reliefs particuliers au niveau des structures ou surfaces de chacun de ces deux éléments 4, 9 assemblés. Ainsi, à titre d’exemple, le moyen de fixation 3 comprend au moins une patte portant une interface de fixation 31 positionnée de chaque côté de l’axe du conduit 4 et de niveau avec la surface d’appui du conduit 4. Ce conduit 4 est alors susceptible de comprendre une ou plusieurs pattes disposées sur sa longueur qui présentent des interfaces sensiblement complémentaires de la surface de la plaque de refroidissement 9 et sont arrangées pour être traversées par des pièces traversantes, telles que des vis, pour coopérer avec des interfaces taraudées portées par la surface de la plaque de refroidissement 9. According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variants, the fastening means 3 comprises a plurality of clipping parts, staples, or screws distributed over the length of the conduit 4 of distribution so that each part of the fixing means 3 performs an anchoring of the distribution orifice 41 with the surface of the cooling plate 9. Depending on the specificity of the fixing means, the anchoring of the duct 4 to the cooling plate 9 is likely to involve particular arrangements or reliefs at the level of the structures or surfaces of each of these two elements 4, 9 assembled. Thus, by way of example, the fixing means 3 comprises at least one lug carrying a fixing interface 31 positioned on each side of the axis of the duct 4 and level with the bearing surface of the duct 4. This duct 4 is then capable of comprising one or more tabs arranged along its length which have substantially complementary interfaces of the surface of the plate of cooling 9 and are arranged to be crossed by through parts, such as screws, to cooperate with threaded interfaces carried by the surface of the cooling plate 9.
[0021] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques des variantes précédemment énoncées, le moyen de fixation 3 comprend une structure ayant la forme d’un cavalier arrangée pour entourer au moins une portion du conduit 4 au niveau d’une section, chacune des deux extrémités du cavalier comprenant une interface de fixation 31 configurée pour interagir avec au moins une partie 92 de la surface de la plaque de refroidissement 9 sur laquelle s’opère la fixation du conduit 4. Selon cette variante de construction, le bord intérieur réalisé par la surface située entre les jambes du cavalier présente préférentiellement un arrangement de forme sensiblement similaire, voire identique, pour être complémentaire de la partie du pourtour du conduit 4 de distribution avec lequel le cavalier du moyen de fixation 3 coopère. Cette complémentarité de forme permet au cavalier du moyen de fixation 3 d’opérer un positionnement et un maintien du conduit 4 qui soient optimisés en épousant au mieux la surface extérieure du conduit 4. Chacune des interfaces de fixation 31 positionnée aux extrémités du cavalier du moyen de fixation 3 opère un ancrage avec la surface de la plaque de refroidissement 9 par coopération avec une ou plusieurs pièces de clipsage, agrafes, ou vis qui interagissent avec des arrangements ou reliefs particuliers portés par la structure ou les surfaces de la plaque de refroidissement 9 et/ou des extrémités du cavalier du moyen de fixation 3. Selon un exemple de réalisation spécifique de cette variante de construction, le moyen de fixation 3 comprend au moins une patte portant une interface de fixation 31 positionnée de chaque côté de l’axe du conduit 4 et de niveau avec la surface d’appui du conduit 4. Ainsi, les extrémités du cavalier du moyen de fixation 3 sont susceptibles de comprendre une ou plusieurs pattes qui présentent des interfaces sensiblement complémentaires de la surface de la plaque de refroidissement 9 et sont arrangées pour être traversées par des pièces traversantes, telles que des vis, pour coopérer avec des interfaces taraudées portées par la surface de la plaque de refroidissement 9. [0022] Selon un exemple de construction se rapportant à une autre variante particulière du dispositif de distribution 1 selon l’invention et susceptible d’être combinée aux caractéristiques des variantes précédemment énoncées, le conduit 4 du liquide caloporteur comprend une structure de recouvrement 44 d’au moins un orifice de circulation 91 d’une plaque de refroidissement 9, cette structure de recouvrement 44 comprenant une pluralité d’orifices de distribution 41 . Selon cette variante de construction, l’orifice de circulation 91 de la plaque de refroidissement 9 comprenant un arrangement en longueur, le conduit 4 est positionné au niveau de l’orifice de circulation 91 de sorte que l’axe du conduit 4 soit disposé dans la longueur de l’orifice de circulation 91. La structure de recouvrement 44 permet ainsi au conduit 4 d’opérer une obturation partielle de l’orifice de circulation 91 en positionnant un ou plusieurs orifices de distribution 41 de dimensions respectives différentes de façon à optimiser la distribution ou l’extraction du fluide caloporteur entre le conduit 4 et la plaque de refroidissement 9. Ainsi, la structure de recouvrement 44, d’une part, présente un dimensionnement au moins supérieur à la surface de l’orifice de circulation 91 de la plaque de refroidissement 9 et, d’autre part, comprend préférentiellement plusieurs ouvertures traversantes le long de sa surface, chacune définissant un orifice de distribution 41 de forme et de dimension respectives. De façon préférentielle, cette structure de recouvrement 44 est structurellement indépendante du reste de la structure du conduit 4 de distribution. Cette structure de recouvrement 44 est ainsi susceptible d’être montée sur la surface de la plaque de refroidissement 9 indépendamment de la fixation du conduit 4 de distribution sur cette même plaque 9. De façon alternative, la structure de recouvrement 44 est maintenue au niveau de la surface de l’orifice de circulation 91 de la plaque de refroidissement 9 par pincement ou compression du conduit 4 de distribution en appui contre la plaque de refroidissement 9. De même, cette structure de recouvrement 44 est susceptible d’être assemblée avec le conduit 4 de distribution avant que ces deux éléments ne soient montés sur la surface de la plaque de refroidissement 9. According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variants, the fastening means 3 comprises a structure having the form of a jumper arranged to surround at least a portion of the duct 4 at the level of a section, each of the two ends of the jumper comprising a fixing interface 31 configured to interact with at least a part 92 of the surface of the cooling plate 9 on which takes place the fixing of the conduit 4. According to this construction variant, the inner edge produced by the surface located between the legs of the rider preferably has an arrangement of substantially similar, or even identical, shape, to be complementary to the part of the circumference of the conduit 4 of distribution with which the jumper of the fixing means 3 cooperates. This complementarity of shape allows the rider of the fixing means 3 to operate a positioning and a maintenance of the conduit 4 which are optimized by marrying the outer surface of the conduit 4 as well as possible. Each of the fixing interfaces 31 positioned at the ends of the rider of the means of fixing 3 effects an anchoring with the surface of the cooling plate 9 by cooperation with one or more clipping parts, staples, or screws which interact with particular arrangements or reliefs carried by the structure or the surfaces of the cooling plate 9 and/or the ends of the rider of the fixing means 3. According to a specific embodiment example of this construction variant, the fixing means 3 comprises at least one lug carrying a fixing interface 31 positioned on each side of the axis of the conduit 4 and level with the bearing surface of conduit 4. Thus, the ends of the rider of the fixing means 3 are likely to comprise a or several lugs which have interfaces substantially complementary to the surface of the cooling plate 9 and are arranged to be traversed by through-parts, such as screws, to cooperate with threaded interfaces carried by the surface of the cooling plate 9 . According to an example of construction relating to another particular variant of the dispensing device 1 according to the invention and capable of being combined with the characteristics of the previously stated variants, the conduit 4 of the heat transfer liquid comprises a covering structure 44 d at least one circulation orifice 91 of a cooling plate 9, this covering structure 44 comprising a plurality of distribution orifices 41 . According to this construction variant, the circulation orifice 91 of the cooling plate 9 comprising a lengthwise arrangement, the duct 4 is positioned at the level of the circulation orifice 91 so that the axis of the duct 4 is arranged in the length of the circulation orifice 91. The cover structure 44 thus allows the duct 4 to operate a partial closure of the circulation orifice 91 by positioning one or more distribution orifices 41 of different respective dimensions so as to optimize the distribution or extraction of the heat transfer fluid between the conduit 4 and the cooling plate 9. Thus, the cover structure 44, on the one hand, has a dimensioning at least greater than the surface of the circulation orifice 91 of the cooling plate 9 and, on the other hand, preferably comprises several through openings along its surface, each defining a dispensing orifice 41 of shape and size respective tension. Preferably, this covering structure 44 is structurally independent of the rest of the structure of the duct 4 for distribution. This cover structure 44 is thus capable of being mounted on the surface of the cooling plate 9 independently of the fixing of the distribution conduit 4 on this same plate 9. Alternatively, the cover structure 44 is maintained at the level of the surface of the circulation orifice 91 of the cooling plate 9 by pinching or compression of the distribution duct 4 resting against the cooling plate 9. Similarly, this covering structure 44 is capable of being assembled with the duct 4 distribution before these two elements are mounted on the surface of the cooling plate 9.
[0023] L’invention se rapporte également à un ensemble caractérisé en ce qu’il comprend au moins un dispositif de distribution 1 selon l’invention fixé à au moins une plaque de refroidissement 9. [0024] Selon un exemple de construction se rapportant à une variante particulière de l’ensemble selon l’invention, au moins une plaque de refroidissement 9 est associée à un dispositif de distribution 1 positionné au niveau des orifices de circulation 91 de chacune de ses extrémités. Selon cette variante, d’une part, un premier dispositif de distribution 1 est monté sur la plaque de refroidissement 9 de façon à opérer l’alimentation du volume intérieur de la plaque 9 en fluide caloporteur et, d’autre part, un second dispositif de distribution 1 est monté au niveau d’une autre partie de la plaque de refroidissement 9 de façon à extraire le fluide caloporteur de l’intérieur de la plaque 9. The invention also relates to an assembly characterized in that it comprises at least one dispensing device 1 according to the invention fixed to at least one cooling plate 9.
